First of all, you cite the "defensive systems" that were adopted back in the 1990s as if they are some kind of problem TODAY -- even though NHL scoring is substantially higher now than it was back then.
Secondly ... goalie pads haven't been an issue in several years. What has changed the most for the goalie position is that the NHL is now filled with goalies who are phenomenal athletes in their own right. Take a look at a random set of video clips from the 1970s and 1980s, and notice how awful the goaltending was back then. That's because we didn't see the first generation of modern, athletic goalies who had been trained as goalies since they were kids until Grant Fuhr and Patrick Roy arrived on the scene in the 1980s. North America was about a decade behind the Soviets when it came to training hockey goalies. Vladislav Tretiak set the standard for modern goaltending in the 1970s, and that was when NHL coaches began to stand up and take note of how much better a goalie could be.
goalies now??....just be 6’6”..put on huge pads and just drop to your knees and let the puck just hit you...
